可同时限制相间过电压的金属氧化物避雷器的特性分析

Study for Characteristics of MOA Arrestor with Limiting Over-Voltage between Phases

本文讨论了在不同的限压措施条件下,相对地及相间绝缘的故障率,表明拟议中的相对地、相间绝缘额定操作冲击耐受电压的取值是可以接受的,说明了四星接法的金属氧化物避雷器对限制相间过电压的有效性,分析了它的参数对限压效果和负载的影响。

Under different over-voltage limiting measures and certain failure rate,this paper shows that these rated withstand switching impulse voltage levels in discussion are acceptable.And it makes explaination about MOAs in cross connection to limit over voltage between phases and some influence from their parameters.
